Special Issue Information

Dear Colleagues,

Wetlands are among the most valuable ecosystems on the planet. They provide an abundance of critical services, supporting people and biodiversity. Wetlands buffer against floods, improve water quality, and are globally significant carbon sinks, sequestering huge amounts of carbon in their soils and vegetation. However, these unique habitats are under immense stress from human developments and climate change. The mapping and subsequent monitoring of wetlands is therefore an important endeavor for their conservation and sustainable management.

The application of remote sensing and Earth observation technologies has advanced wetland research by enabling detection and characterization across multiple spatial scales. Despite this progress, significant challenges remain, particularly in capturing the fine-scale complexities and hydrological regimes of wetlands, as well as the need for large and reliable training datasets. Emerging approaches using artificial intelligence (AI) and machine learning, including deep learning and neural networks, are beginning to address these limitations. These technological advancements hold great promise for improving wetland mapping and monitoring.

This Special Issue, in line with Remote Sensing’s emphasis on data and methodological innovations, focuses on recent advances in the remote sensing of wetland ecosystems, with particular attention to developments in AI and machine learning. We welcome studies addressing the following themes:

  • Advances in AI and machine learning for wetland mapping and monitoring;
  • Deep learning and neural networks for automated wetland detection, classification, and delineation;
  • Data and sensor fusion for enhanced wetland characterization;
  • Time-series analysis and change detection modeling of wetland dynamics;
  • Transferability and scalability of AI models across regions and wetland types;
  • Cloud-based machine learning platforms (e.g., Google Earth Engine) for wetland applications;
  • Case studies showcasing innovative AI and machine learning applications in wetland remote sensing.

Arctic–boreal wetlands and lakes are among the most significant and most uncertain natural sources of atmospheric methane. Rapid Arctic amplification, permafrost thaw, hydrological change, and increasing ecosystem productivity are expected to intensify methane emissions from high-latitude landscapes. Yet, significant uncertainties persist in quantifying their magnitude, seasonality, and spatial distribution. This review synthesizes the current state of the art in monitoring methane emissions from Arctic–boreal wetlands and lakes through complementary bottom-up and top-down approaches. We examine Earth observation (EO) capabilities, including optical, thermal infrared (TIR), and synthetic aperture radar (SAR) missions, as well as new emerging satellite platforms. We also assess in situ measurement networks, wetland and lake inventories, empirical and process-based models, and atmospheric inversion frameworks. Key gaps remain in representing small waterbodies, shoreline heterogeneity, winter emissions, inventory harmonization, and integration between atmospheric retrievals and surface-based flux models. Moreover, advances in multi-sensor data fusion, explainable artificial intelligence (XAI), physics-informed inversion methods, and geospatial foundation models offer strong potential to reduce these uncertainties. A coordinated integration of satellite observations, field measurements, and transparent modeling frameworks is essential to improve Arctic–boreal methane budgets and strengthen projections of climate feedback in a rapidly warming region.
